INGRAM PATTERN GRADING DEVICE 3 Sheets-Sheet 3 Filed April 2,1954 INVENTOR DZXQ/V JVGRM United States Patent r' 2,711,588 1C6Patented June 28, 1955 PATTERN GRADING DEVICE Dixon Ingram, Brooklyn, N.Y. Application April 2, 1954, Serial No. 420,715 7 Claims. (Cl. 33-12unskilled and'skilled alike, particularly in tailoring and garment anddress making, to hold a pattern of one size and move it over anunderlying piece of material the correct requisite distances. in anydirection to enlarge or reduce the pattern to another standard size,such as from a size 38 to a size 40.

Another object of the invention proposes constructing the grading devicewith a carriage movable accurate distances along a base plate and havinga cross plate secured to it which contains a cross slide similarlymovable along it with means to adjust the freedom of the movement ofeach.

As another object, the presentinvention proposes providng two spacedpattern holding arm members removably and adjustably secured to thecross slide andadapted conveniently to hold orrelease a pattern piece atany desired position with relation to the cross slide.

A further object of the present invention proposes forming the crossslide with adjustment knobs which not only will properly hold thepattern holding arm members but can also be used to lock the slide inany desired position when this is necessary or desirable.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will'be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the inventionare more particularly set forth.

On the accompanying drawings forming a material part of this disclosure:

Fig. 9 is a fragmentary perspective view similar to Fig. 1 butillustrating a modification of the present invention. Fig. 10 is asectional view taken on line 10--10 of Fig.9. f Y The pattern gradingdevice, in accordance with the first form of the invention illustratedin Figs. 1 .to 8, inclusive, has a base plate 15, preferably made ofmetal, such as cast aluminum or chrome plated steel, but which may be ofplastic, wood or other material.

Base plate 15 is rectangular with a dove-tail groove 16 in its upperface 17, extending the full length of the base plate.

Slidably mounted in the dove-tail groove 16 of base plate 15 is a wedgeshaped carriage 18 having a rack channel or groove 19 (see Fig. 7) inits bottom face 20 and a pinion chamber or recess 21 adjacent the groove19 in the bottom face 20. The rack channel or groove 19 extends the fulllength of carriage 18.

* Carriage 18 also contains a knob shaft opening 21, extending from itsupper face to the center of the pinion chamber or recess 22. A pinion 23is rotatably mounted in the pinion chamber 22 being fixed to the shaft24 of a turning knob 25 extending above the upper face of the carriage18.

A calibrated scale 26 is secured to base plate 15 adjacent carriagegroove 16 and the carriage 18. Pointer 27 is fixed to the carriage andoverlies the scale 26 for movement along the scale. A rack bar 28 isfixed to base plate 15 in groove 16. The rack bar 28 is disposed on thebase plate as to fit within the rack channel or groove 19 of thecarriage 18 when the carriage is slidably mounted in the carriage groove16 of base plate 15. Rack bar 28 has teeth 29 adapted to mesh with teeth30 of pinion 23 so that movement of the pinion by knob 25 will move thecarriage along the rack bar.

Also mounted in the carriage groove 16 of base plate 15 is a carriageshim adjustment plate 31 which rests against one side 32 of thecarriage. Set screws 33, extending through the base plate 15, providemeans to bias the plate 31 against the carriage to thereby adjust thesliding freedom of carriage 18. Enough pressure should be provided onthe carriage by plate 31 so that the carriage will stay in any desiredposition and the pointer will remain on any selected calibration on thescale.

Fixed to one end of the carriage 18 and to the upper surface or face ofthe carriage is a cross plate34. Cross plate 34 has a dove-tail groove35 in its upper face 36 extending the full length of the cross plate.the cross plate is constructed in a manner similar to the base plate andis of the same material. The cross plate, however,has an additonalrecess 37, in which is secured a rack bar 38.

A cross slide 39, wedge shaped in cross section, is

slidably mounted in the cross slide groove 35 of cross plate 34. Thecross slide 39 is of similar construction to carriage 18 and preferablyis of the same material. Cross slide 39 has a rack bar groove 40 in itsbottom face 41 and a pinion recess 42 at one-side of the rack bar groove40. A pinion 43 is rotatably mounted in the pinion recess or chamber 42.A pinion turning knob 44 is mounted on the cross slide. Knob 44 includesa shaft 45, which extends through an opening 46 in the upper face of thecross slide 39, and to which the pinion 43 is secured.

A cross slide shim adjustment plate 48 is mounted in the groove 35 ofcross plate 34 adjacent the cross slide. Set screws 49 extend throughthe cross plate "48 to provide means for bringing plate 48 against crossslide 39.

A second calibrated scale 50 is secured to the upper face 36 of thecross plate 34 adjacent the cross slide groove 35 and cross slide 39. Asecond pointer 51 is fixed to cross slide and extends over the scale 39for movement along the scale.

Adjustably and removably secured to the cross slide 39 by knurled headedscrews 52are a pair of spaced pattern holding arm members 53. Patternholding arm members 53 are identically constructed, each having apluralityof spaced securing openings 54 at one end for extending orshortening purposes, and aclip type clamp 55 at the other end.

Preferably Clamps each have a lower arm 56 and an upper arm 57 whicharms. are pivotally connected by hinge brackets 58 and 59 and hinge pin60 intermediate their ends. A pair of spaced pattern holding pins 61 and62 are secured to the lower face of each upper arm 57- and a pair oflike spaced pin openings 63 are provided in each lower arm 56 to receiveonly the tips. of the pins 61 and 62;. A coil spring 64 around thehinge: pin 60 and between the up per and lower arms 56 and 57 biases thefree ends of the arms together with the tips of the pattern holding pins61 and 62 seated in the pin openings: 63.

The knurled headed screws 52 have shoulder portions 65 which bearagainst the lower arms 56 adjacent the securing openings 54 to hold themembers: 53 in any desired position.

' The pattern grading: device is shown to be secured to a metal base.plate 80' formed with u-flange 8.1. A plurality of clamping screws 82are provided along U -flange 81 for clamping. the device to a. table orother support.

The operation of the grading device is as fol-lows. A pattern piece 66,for grading a material 67, (see Fig. 4*); is. placed in the jaws ofmembers 53' and is gripped by teeth 62. The pattern thus rests on thematerial being graded. The garment size is then obtained by tracingaround the edges of pattern 66. When different, and larger, sizepatterns are desired, arms 53 are moved longitudinally by actuation ofcross-slide 39 until the required size is determined oil by indicia 50.The outline of pattern 66 along the sides thereof is traced. Base plate15 is then moved at right angles thereto. as determined by scale 26, andthe pattern: size is marked: off. This composite will give the desired:larger graded pattern. In this manner, any size pattern isobtained by asingle instrument.

The modification of the presentinvention illustrated in Figs. 9 and 10is characterized by the provision of a cross slide 68 and cross plate 69similar to cross" slide 39 and cross plate 34 described above and withlike parts given the same reference numbers but primed to distinguishthe figures. Cross plate 69 however,- has a plurality of screw endreceiving openings 70 spaced in accor-dance with the calibrations onscale 50 and cross slide 68-has threaded screw'openings-7-1 (only oneshown to receive a knurl headed screw 72 to hold pattern hold ing armmembers 53' to the cross slide. A resilient ring 73 fits around: screw72 under its head 74- normally' tohold tip' end 75' of the screwout ofengagement with: cross plate openings 70 so that cross slide can movealong the cross plate. Tightening the screw 72 however compresses thering 73 and permits the tip end 75 of the screw to engage any selectedone of the openings 70. The operation of Figs. 9- and 10 is similartothat of Figs. 1 to 8, in all other respects. 7

While specific arrangements of parts and details of construction havebeen shown, these are for purposes of illustrationonly, andmodifications may be made by persons skilled in the art withoutdeparting from the" spirit of the invention, as determined by the scopeof the claims.

Having thus described my invention, What I claim as new and desire tosecure by United States Letters Patent is:
